Question: A nurse in a clinic is caring for a client who has suspected anemia. Which of the following laboratory
test results should the nurse expect?
A. Iron 90 mcg/dL
B. RBC 6.5 million/uL
C. WBC 4,800 mm3
D. Hgb 10 g/dL
Answer: A. An iron level of 90 mcg/dL is within the expected reference
range and is not an expected finding of anemia.
B. RBC count of 6.5 million/uL is above the expected reference
range. A decreased RBC count is an expected finding of anemia.
C. WBC count of 4800 mm3
is below the expected reference range and is not an expected finding of anemia.
D. CORRECT: Hgb of 10 g/dL is below the expected
reference range and is an expected finding of anemia.
Question: A nurse is caring for a client who is receiving warfarin for anticoagulation therapy. Which of the
following laboratory test results indicates to the nurse that the client needs an increase in the dosage?
A. aPTT 38 seconds
B. INR 1.1
C. PT 22 seconds
D. D‑dimer negative
Answer: A. aPTT is monitored for clients receiving heparin therapy. An aPTT of 38 seconds is within
the expected reference range for clients not receiving heparin therapy.
B. CORRECT: INR of 1.1 is within the expected reference range for a client who is not
receiving warfarin. However, this value is subtherapeutic for anticoagulation therapy. The nurse should expect
the client to receive an increased dosage of warfarin until the INR is 2 to 3.
C. PT of 22 seconds is above the expected reference range for a client receiving warfarin
therapy. This result indicates the client is at an increased risk for bleeding.
D. A negative D‑dimer test indicates the absence of a pulmonary embolus or deep vein
thrombosis and is not used to determine the dosage needs for warfarin therapy.
Question: A nurse is providing teaching for a client who is scheduled for a bone marrow biopsy of the iliac
crest. Which of the following statements made by the client indicates an understanding of the teaching?
A. "This test will be performed while I am lying flat on my
back."
B. "I will need to stay in bed for about an hour after the test."
C."This test will determine which antibiotic I should take for treatment." D."I will receive general anesthesia for
the test."

position during the test in order to expose the iliac crest.
B. CORRECT: The nurse should inform the client of the need to stay on bed rest for 30
to 60 min following the test to reduce the risk for bleeding.
C. The nurse should inform the client that a culture and sensitivity test determines the
type of antibiotics needed to treat an infection.
D. The nurse should inform the client that he will receive a sedative prior to the test and
that a local anesthetic will be used at the site.
, Question: 1. A nurse is preparing to administer
packed RBCs to a client who has a Hgb of 8 g/dL. Which of the following actions should the nurse plan to take
during the first 15 min of the transfusion?
A. Obtain consent from the
client for the transfusion.
B. Assess for an acute
hemolytic reaction.
C. Explain the transfusion
procedure to the client.
D. Obtain blood culture
specimens to send to the lab
Answer: A. The nurse should obtain consent from the client for
the transfusion prior to initiating the transfusion.
B. CORRECT: The nurse should assess for an acute hemolytic reaction
during the first 15 min of the transfusion. This form of a reaction can occur following the transfusion of as little
as 10 mL of blood product.
C. The nurse should explain the transfusion procedure
to the client prior to initiating the transfusion.
D. The nurse should obtain blood culture specimens
Question: 2. A nurse is caring for a client who
is receiving a blood transfusion. Which of the following actions should the nurse expect if an allergic
transfusion reaction is suspected? (Select all that apply.)
A. Stop the transfusion.
B. Monitor for hypertension.
C. Maintain an IV infusion with
0.9% sodium chloride.
D. Position the client in an
upright position with the feet lower than the heart.
E. Administer diphenhydramine.
Answer: A. CORRECT: The nurse should immediately stop the infusion if an allergic transfusion
reaction is suspected.
B. The nurse should monitor for hypotension if an allergic transfusion reaction is
suspected due to the risk for shock.
C. CORRECT: The nurse should administer 0.9% sodium chloride solution through new
IV tubing if an allergic transfusion reaction is suspected.
D. The nurse should position the client in an upright position with the feet lower than the
level of the heart if a circulatory overload is suspected.
E. CORRECT: The nurse should administer an antihistamine, such as diphenhydramine,
if an allergic transfusion reaction is suspected.
